Reclaim Your Lifestyle with Minimally Invasive SI Joint Fusion
Many patients with chronic low back pain — 15-30% — may have pain caused by dysfunction of the sacroiliac (SI) joint.1-4 The SI joint is also a pain generator in up to 43% of patients with continued or new-onset lower back pain after a lumbar fusion.5
Dr. James Weimar is pleased to offer patients treatment for SI joint dysfunction which utilizes a minimally invasive surgical technique. Sacroiliac joint fusion with the iFuse Implant System® is clinically proven to be effective in treating SI joint pain.
Watch this video to see how the iFuse Implant System works.
88% of patients report improved pain, function and quality of life.6
Causes of SI Joint Pain
The sacroiliac joint (SI joint) is located in the pelvis. It links the iliac bones (pelvis) to the sacrum (lowest part of the spine above the tailbone) and is an essential component for energy transfer between the legs and the torso.
Like any other joint in the body, the SI joint can be injured and/or undergo degeneration. When this happens, people can feel pain in their buttocks and sometimes in the lower back, hips and legs. This is especially true while lifting, running, walking or even lying on the affected side.
Symptoms of SI Joint Dysfunction
In addition to pain in the lower back or spine, SI joint dysfunction can produce sciatica-like symptoms, with symptoms present in the buttocks, pelvis, groin, or sometimes in the legs. Chronic SI joint pain symptoms can make it difficult to perform common daily tasks and can affect every aspect of a patient’s life.
People with SI joint dysfunction can even experience impaired function. With symptoms being similar to those of other conditions of the lumbar spine, pelvis and hip, an SI joint examination is crucial to properly diagnosing the origin of the pain.
Do you experience one or more of these symptoms?
- Lower back pain
- Sensation of the low extremity: pain, numbness, tingling, weakness
- Pelvis/buttock pain
- Hip/groin pain
- Feeling of leg instability (buckling, giving way)
- Disturbed sleep patterns due to pain
- Disturbed sitting patterns (unable to sit for long periods, sitting on one side)
- Pain when going from sitting to standing
Benefits of SI Joint Fusion with the iFuse Implant System
Traditional sacroiliac joint fusion involves open surgery that may last up to a few hours. Open surgery includes a surgical incision to access the joint, removal of cartilaginous material from the joint, and use of bone grafts and screws to help fuse the joint. Patients typically require a several-day hospital stay.
Alternately, the iFuse procedure is a minimally invasive surgical option, meaning that it requires a smaller surgical incision, less time in surgery (about an hour), and potentially a faster healing process.
The iFuse Implant System is designed to stabilize and fuse the SI joint. The procedure involves inserting typically three triangular-shaped titanium implants across the sacroiliac joint to maximize joint stability, reduce pain and improve function. The iFuse procedure may not require an overnight stay at the hospital.
The patented iFuse implant has been clinically evaluated more than any other SI joint fusion procedure. More than 100, peer-reviewed publications demonstrate the safety, durable effectiveness, and biomechanical and economic benefits of the iFuse implant. It is the only SI joint fusion device with clinical studies demonstrating that treatment improved pain, patient function and quality of life.6-11
Making a Diagnosis
A variety of tests performed during physical examination may help reveal the SI joint as the cause of your symptoms. Sometimes X-rays, CT-scan or MRI may be helpful in the diagnosis because they can rule out other common sources of pain — such as your lumbar spine or hip joints. It is also important to remember that other conditions (like a disc problem) can co-exist with SI joint disorders.
The most reliable method for accurately determining whether the SI joint is the cause of your pain is to inject the SI joint with a local anesthetic. This diagnostic injection will be performed under either X-ray or CT guidance to verify the accurate placement of the needle in the SI joint. If your symptoms decrease by at least 50%, it can be concluded that the SI joint is either the source of or a major contributor to your pain. If the level of pain does not change after the injection, it is less likely that the SI joint is the cause of your pain.
Once the SI joint is confirmed as the cause of your symptoms, treatment can begin. Some patients respond well to physical therapy, use of oral medications or injection therapy. These treatments are often performed repetitively, relief of symptoms is often temporary. If non-surgical treatment options have been tried and don’t offer long-term relief, it may be time to consider the minimally invasive iFuse procedure.
Dr. Weimar will assess your condition and discuss treatment options for you.

NOTE: Individual results vary. As with any minimally invasive surgical procedure, there are potential risks associated with the iFuse Implant System. It may not be appropriate for all patients and all patients may not benefit. The iFuse Implant System® is by SI-Bone®. For more information on the technology, you can visit SI-Bone’s website.
